What is an example of meta-analysis?
For example, if there are two groups of patients experiencing different treatment effects studies in two RCTs reporting conflicting results, the meta-analytic average is representative of neither group, similarly to averaging the weight of apples and oranges, which is neither accurate for apples nor oranges.
What kind of study is a meta-analysis?
Meta-analysis is a quantitative, formal, epidemiological study design used to systematically assess the results of previous research to derive conclusions about that body of research. Typically, but not necessarily, the study is based on randomized, controlled clinical trials.
How do you know if an article is a meta-analysis?
In most Library databases, you can find meta-analysis research articles by using meta analysis as a search term. There are a few databases that have special limiters for publication type or methodology in the advanced searching section.

- 1) Formulate research question.
- 2) Identify relevant literature.
- 3) Extract and consolidate study-level data.
- 4) Data appraisal and preparation.
- 5) Synthesize study-level data into summary measure.
- 6) Exploratory analyses.
- 7) Knowledge synthesis.

| Levels of Evidence | |
|---|---|
| Level I | Evidence from a systematic review or meta-analysis of all relevant RCTs (randomized controlled trial) or evidence-based clinical practice guidelines based on systematic reviews of RCTs or 3 or more RCTs of good quality that have similar results. |
